A differential horizontal motion conveyor and drive mechanism for conveying or feeding a variety of goods. A plurality of configurations is provided in which rotar y motion is converted to reciprocating motion by a crankshaft. The horizontal motion conveyor consists of an elongate trough that can functionally operate as an inertial type reciprocating conveyor. That is, to move in one direction, accelerating the conveyed material, then reverse direction as the inertia of the material continues to propel it forward thus conveying it. In another embodiment, it may functionally operate as a slow forward/fast return reciprocating conveyor. That is to carry material forward in a first slow speed, then to accelerate and reverse direction at higher second speed. This second speed sufficient to overcome static frictional forces between the conveyor trough and the material, thus conveying it. In yet another embodiment, the drive mechanism may be attached to a spiral or helical trough, functionally operating in either of the afore mentioned motions, thus vertically conveying said material. The slower of th e two desired trough speeds is derived by direct connection to a substantially constant speed motor or other prime mover. The faster of the two desired trough speeds is accomplished by mechanical disconnection from said motor by a mechanical uni-directional clutch/bearing , and acceleration of the conveyor trough by tension or compression device such as a spring. Th is provides for a low noise, simple, reliable and economical drive and conveyance system.</SDO AB>
